These sensors show an * and report in steps (10–20 cm). Treat them as a warning that water is standing, not as an exact depth.

Check 3 things before you leave home

  1. Water on the road: BMA road flood map weather.bangkok.go.th/flood
  2. Traffic and cameras: Longdo Traffic or BMA CCTV
  3. Rain on the way: Thai Meteorological Department radar weather.tmd.go.th

Do not drive or walk through fast-flowing water. Watch out for open drains and electrical leaks near power poles and billboards.

Frequently asked questions

Where does this data come from?

From road-flood sensors of the Bangkok Metropolitan Administration's Drainage and Sewerage Department, published in real time at weather.bangkok.go.th/flood

How deep is too deep for a sedan?

Around 30 cm or more risks water getting into the engine, and fast-flowing water only 30 cm deep can sweep a sedan away. Avoid that route.

Who do I call if I'm stranded by floodwater?

Call the DDPM hotline 1784 or add LINE @1784DDPM. If anyone is injured, call 1669.

How can I tell if more heavy rain is coming?

Check the TMD rain radar and the forecast map on this site's home page.
